Well .... Everything deserves a chance now and then
Yes, that's true, I did the same but the other way, being an Android user for the past 6 years I gave it a try to the 7 Plus and Apple Watch, for 3 months nothing but the iPhone and boy I was bored, if it wasn't for the Watch I wouldn't have lasted a month.
After a while I used the phone just for a couple of hours a day and the rest I did it on the Watch. Definitely not my cup of tea, I don't let a company dictate with some exclusive features the phone I want to use. Even with my wife and daughters with iPhones I barely used iMessage, we only use WhatsApp and basically never used or need FaceTime. So no big deal to me switching between iOS or Android.
It never ceases to amaze me the amount of users that try Android for the first time coming from iOS and simply don't give it a fair try, they simply pretend to keep using things just like they did with iOS and that is just a recipe for a big frustration and disappointment, hence the reason I always suggest to read about the dozens of things you have never used and see this videos with all those tips and tricks and I always guarantee that it will change your perspective completely.
So, just go to the
